Why is it taking so long?
I have a pipe, which can fill water in a beaker in 6 hours. But, there is a hole at the bottom of the beaker that can empty the same beaker which is full of water in 8 hours.
How much time (in hours) will the pipe take to fill the beaker. If the hole is also opened?
Assumptions: The beaker is to be assumed empty when the pipe and hole are opened to fill and empty it respectively. Water is flowing out at a constant rate, regardless of the depth of the water.
